EDF stated that upgrading these reactors to meet the safety requirements of newer European Pressurised Reactor models will cost an estimated 6 billion euros. Preparatory work on the first reactor began in 2024. “Raising the safety standards to match those of newer European Pressurised Reactor models would cost an estimated 6 billion euros,” EDF said in a statement.
The initiative aligns with French President Emmanuel Macron’s strategy to bolster nuclear energy production by extending the life of existing reactors and constructing at least six new ones in the coming decades. This effort aims to strengthen France’s energy infrastructure.
EDF faces challenges, including financial constraints and past project delays. The company, fully nationalized in 2023 with a state investment of approximately 10 billion euros, has also dealt with budget overruns and reactor defects. Newly appointed CEO Bernard Fontana is exploring options to fund these upgrades, including potential asset sales, to support both existing reactor enhancements and new construction projects.
The ASN outlined that it will provide specific safety requirements for each of the 20 reactors during their 40-year inspections. EDF is also required to submit annual progress reports to ensure compliance with these standards. The reactors, part of France’s 56-reactor fleet, are scheduled to reach their current approved lifespan between 2026 and 2040. The ASN previously approved extensions for EDF’s 32 smaller 900MW reactors.
This development reflects EDF’s commitment to maintaining a reliable energy supply while meeting modern safety standards. The upgrades are expected to support France’s long-term energy goals, ensuring the continued operation of its nuclear facilities.
